在for循环中绘制R中boxplot的分位数值 [英] Plotting Quantiles values of boxplot in R inside a for loop
本文介绍了在for循环中绘制R中boxplot的分位数值的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
名称< - 名称(空调)
类<-sapply(airquality,class)
airquality [is.na(airquality)] < - 0
for(name in name [classes =='numeric']){
boxplot(airquality [,name])
}
现在我想显示所有分位数值,即First分位数,中位数,第三分位数和平均值,如下图所示。我在网上搜索了很多,但没有找到任何适合我需要的东西。以下是我想要绘制的图表:
解决方案
下面是一个例子,只是使用Wind属性。
B = boxplot(airquality [,Wind])
text(1.3,B $ stats,B $ stats)
IQR = B $ stats [4] - B $ stats [2 ]
segments(0.5,c(B $ stats [2],B $ stats [4]),0.7,c(B $ stats [2],B $ stats [4]))
text (0.6,B $ stats [3],IQR)
箭头(0.6,B $ stats [3] +0.5,0.6,B $ stats [4] -0.1,0.1)
箭头(0.6, B $ stats [3] -0.5,0.6,B $ stats [2] +0.1,0.1)
Suppose I have a data frame airquality. I made a for loop to plot all the boxplot of the air-quality data set.
name <- names(airquality)
classes<-sapply(airquality,class)
airquality[is.na(airquality)] <- 0
for (name in name[classes == 'numeric']) {
boxplot(airquality[,name])
}
Now I want to display all the Quantiles values i.e. First Quantile, Median, Third Quantile and mean as in the below image. I searched the web a lot but didn't find anything that suits my need. Below is the desired graph which I want to plot:
解决方案
Here is an example, just using the "Wind" attribute.
B = boxplot(airquality[,"Wind"])
text(1.3, B$stats, B$stats)
IQR = B$stats[4] - B$stats[2]
segments(0.5, c(B$stats[2], B$stats[4]), 0.7, c(B$stats[2], B$stats[4]))
text(0.6, B$stats[3], IQR)
arrows(0.6, B$stats[3]+0.5, 0.6, B$stats[4]-0.1, 0.1)
arrows(0.6, B$stats[3]-0.5, 0.6, B$stats[2]+0.1, 0.1)
